Original title: One-point garbage disposal saves major events. Professionals say that garbage sorting can save a lot of costs from transportation to terminal treatment.

Shenzhen Special Zone News August 17, 2019 Recently, this newspaper reported four modern environmental protection power plants in Shenzhen, which aroused widespread concern in society. Some citizens are wondering, since Shenzhen has such a large amount of garbage incineration and advanced technology, is it necessary to classify garbage? In interviews and surveys, professionals in garbage disposal emphasized that garbage disposal costs a lot, and the mixed garbage disposal process is more complicated. Garbage classification not only saves resources but also reduces the burden of garbage disposal. Only when everyone cares about garbage disposal and starts to do garbage sorting well can the dilemma of "garbage besieged city" be fundamentally alleviated and social spiritual civilization be promoted.

The road from the community to the terminal facilities is long.

The high cost of garbage disposal calls for classification.

The daily average domestic garbage removal in Shenzhen increased from 7.5 tons in 1979 to 19,000 tons in 2018, exceeding 2,500 times, with an annual growth rate of 6%, and with the rapid development of Shenzhen, the growth rate is still increasing year by year. It is understood that some landfills are designed to have a service life of up to ten years or even decades, but they can’t resist the growing amount of garbage. Some landfills are filled in advance and garbage incineration plants are overloaded.

The relevant person in charge of the Municipal Urban Management and Comprehensive Law Enforcement Bureau said that while building garbage disposal facilities, the amount of garbage has increased. For many years, Shenzhen garbage disposal facilities have encountered difficulties in site selection, landing and construction. Zhong Rigang, deputy general manager of Shenzhen Energy and Environmental Protection Co., Ltd., who is responsible for the construction and operation of four energy and ecological parks in our city, also believes that "building garbage disposal facilities will cost a lot, not only spending money, but also occupying social resources."

There is still a long journey from the community to the terminal treatment facilities. From the community, it will be transported to the garbage transfer station in the form of vehicle-mounted drums or vehicle-mounted bags, and then it will be reduced in water and compressed, and then it will be pulled to the garbage incineration power plant or sanitary landfill for final treatment by the garbage truck.

"Every link will generate costs. In order to prevent the impact on residents’ lives and the urban environment, in the transportation process, the garbage with odor is transported by special closed vehicles." Zhong Rigang believes that if citizens can reduce their sources at home, they will not use so many more expensive closed cars.

"Garbage came in and was destroyed? Garbage disposal is very complicated. " Zhong Rigang analyzed that if the garbage is not classified as mixed garbage, the treatment standard will be determined according to the most dangerous components, the treatment process is more complicated, and more environmental protection facilities and materials are invested. Despite the garbage disposal facilities, Zhong Rigang appealed that everyone is a garbage producer and should actively participate in garbage sorting, reduce garbage production at the source and share the pressure of garbage disposal. Sorted garbage is more convenient to transport and treat, and reduces the cost.

More than 100 enterprises participate in transportation processing.

Put an end to garbage before sorting and then mixing.

Large pieces of garbage, glass plastic paper, kitchen waste, waste lamps, waste batteries … The reporter saw in Langlujiayuan Community of Nanshan District that these classified garbage were collected and transported by vehicles with different logos and different enterprises. This scene is the normal state of garbage removal in the community that promotes garbage sorting in Shenzhen.

How to ensure classified transportation of classified garbage? Will the garbage that residents have worked hard to sort out be taken away by a car? Huang Zhibin, director of the comprehensive department of Shenzhen Municipal Domestic Waste Classification Management Affairs Center, said that the removal unit was invited by the district governments and had certain qualifications. All kinds of garbage were removed by different removal companies. According to the contract, the types of garbage cleaned by each removal company were different, and the mixed collection and transportation of garbage was eliminated from the system. Due to the different operation projects of enterprises, collecting garbage collected and transported by non-self enterprises will not generate benefits, and enterprises are not driven by interests.

It is reported that there are more than 10 enterprises responsible for the collection, transportation and treatment of waste furniture, waste battery lamps, waste glass plastic paper, annual oranges, waste fabrics, green garbage, fruit and vegetable garbage and kitchen garbage in Futian District, more than 20 enterprises in Luohu District, more than 50 enterprises in Baoan District and 10 enterprises in Longgang District, and more than 100 enterprises are responsible for the classified transportation, classified treatment and recycling of garbage in the city.

Remove the floor trash can before the end of the year.

Citizens need to go downstairs and throw garbage.

As early as 2015, Shenzhen began to fully implement garbage sorting. After the garbage is sorted, how to throw it away? In order to improve the participation rate and accuracy of residents, after repeated exploration, Shenzhen is now vigorously promoting the residential waste classification model of "centralized classified delivery+regular fixed-point supervision", that is, there is no trash can on the floor, and centralized classified delivery points are set downstairs. Arrange supervisors to conduct on-site supervision at the centralized waste sorting and dropping point in the community from 7: 00 to 9: 00 every night.

In the first half of 2019, the city built 805 residential areas with the mode of "centralized classified delivery+regular and fixed-point supervision", and implemented the classified delivery of kitchen waste at regular and fixed points (7: 00-9: 00 every night), and recruited party member, volunteers, enthusiastic residents and property managers as supervisors. At present, there are 2,671 supervisors in the city to conduct on-site supervision at 2,630 centralized delivery points in 805 communities, covering a total of 452,000 households and 1.53 million residents, and each centralized delivery point serves about 172 households on average.

According to the Municipal Urban Management and Comprehensive Law Enforcement Bureau, by the end of the year, this model will be extended to all 3,600 residential areas with property management in the city. This means that in many communities where garbage bins are placed on the floors, all these bins should be removed, and garbage sorting points should be set up again in the communities, and the garbage should be carried downstairs for sorting.

At present, Shenzhen is carrying out the action of removing barrels, and strives to completely remove the garbage bins on the residential floors before the end of this year. Although not every residential area has garbage bins on the floor, some residential areas have no garbage bins on the floor since they first moved in. It is necessary to change the habit of throwing garbage when they go out for many years, especially in high-rise residential buildings. Whether residents will adapt and support the withdrawal of buckets will test the relevant departments of the district and street. (Shenzhen Special Zone Daily reporter Lin Qingrong)
